- Tired mastic found when preparing windows for paint

Sand mastic for homes and businesses in Stepps
Traditional burnt sand mastic blends with stone and brick surrounds. It suits period and listed homes where a modern sealant bead would stand out. We are often asked to deal with a silicone bead on a sash window that spoils the look and tired mastic found when preparing windows for paint, across timber door frames, sash and case windows and stone surrounds.
Outdoor sealant needs a dry surface, so window work around Stepps is planned around the weather, and longer journeys are planned in advance. Let us know about access to every frame, including any upstairs.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we’ll put it right.

Signs you need sand mastic in Stepps
Some old mastic was never deep enough. A thin layer doesn’t hold well, which is why we pack deep voids first and get the depth right.
People normally contact us after spotting something like this:
- Tired mastic found when preparing windows for paint
- A silicone bead on a sash window that spoils the look
- Old sand mastic that has cracked, crumbled or fallen out
- Gaps where the frame meets the masonry
Letting a property close to Stepps station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.

Sand mastic in Stepps: local notes
Historic houses like Provand's Lordship (about 4.3 miles south-west) are a reminder that the area around Stepps has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Many older homes in Scotland have sash and case windows, and the joint between the box frame and the stone or render is traditionally pointed with sand mastic.
For site and facilities teams at buildings such as Chryston High School, larger buildings have plenty of frames, and the mastic around each one ages. Provand's Lordship, about 4.3 miles south-west, is one of the historic houses in the wider area around Stepps, and older homes nearby need a sealant that suits their walls.

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Look over the window mastic once a year
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid patching sand mastic with silicone
Do not touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Once mastic starts to crumble, rain gets in. That water can reach the timber frame and the wall, so renewing it early is worth it.
How it works
You don’t need to clear the whole room or building, just the space around the work. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. Somewhere like Stepps may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we agree which joints need doing.
- We remove the old, loose mastic.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
